Let marks scored by 1st student = $$x$$ => Marks scored by another student = $$(x + 22)$$ According to question, => $$(x + 22) = frac{55}{100} imes (x + x + 22)$$ => $$x + 22 = frac{11}{10} imes (x + 11)$$ => $$10x + 220 = 11x + 121$$ => $$x = 220 - 121 = 99$$ $$ herefore$$ Marks scored by other student = 99 + 22 = 121
